Horn walked out of Superior Court in New Haven a free man on April 25.

"What took place against me by this criminal justice system is a tragedy, a crime against humanity, and an assault against justice and the United States Constitution. I hope this never happens to anyone else," Horn said by way of a release at that time.

The case against Horn stemmed from a robbery at Dixwell Deli on Jan. 24, 1999, during which customer Caprice Hardy was murdered. Horn was 17 when New Haven police accused him of the crime.

The conviction of a second suspect, Marquis Jackson, was vacated in May.
